The CPS (Camshaft Position Sensor) is one of the weakest links on the Ford 7.3 Powerstroke engines. The sensor has a high
failure rate and common symptoms include having the engine die while driving as if you turned the key off just to have the
driver pull over and restart without any problems; periodic 'hiccupping' of the engine; complete failure of the CPS can kill the engine
and will not let it restart.

I have read where Ford dealerships have been known to charge as much as $45 for a CPS
at the parts counter,
$650 parts and labor for the service department to change it out. You can do it yourself for a small fraction of that price.

Since the original black CPS has been recalled and is no longer available, DieselOrings.com has the
BLUE CPS and
GREY CPS in stock.
With just a few simple hand tools and a little know-how, you can do this and save some serious greenbacks. There is a
different CPS for the 94.5-97 (98 E-series) (dark blue) from the CPS for the 99-03 (grey) 7.3L engines.

Tools to change out the CPS

First, locate the existing CPS, looking at the front of the engine, it is about the 10 o'clock position on the flywheel dampener.

from the top

The CPS can be accessed easiest from under the truck.
Disconnect the electrical connector from the CPS by gently lifting on the locking tab and pulling the plug from the CPS.

Using the 10mm 6pt socket, make sure the socket fully engages the entire bolt head so you do not strip the bolt shoulders
and loosen. Once the bolt is broken loose, it should come out easily.

Swivel the timing mark indicator slightly out of the way and position a pry bar or large screwdriver between the CPS and
engine block and gently pry the CPS out of its mounting hole. Once the o-ring clears the engine block, you should be able to
reach up and remove the CPS.

Prepare the new CPS for installation by lubing the o-ring with engine oil or a light coating of grease.

Put a small amount of anti-seize lubricant on the 10mm bolt.

Insert the new CPS in the engine block hole and push it in as far as you can by hand. Do not worry if it does not
completely seat. Using the timing mark indicator, rotate the CPS so you can insert the 10mm bolt and tighten.

Use a small amount of dielectric grease on the watertight fins of the plug. Do not get any of the grease on the metal
contacts as it will prevent electrical continuity and will not allow the CPS to work properly. Insert the plug into the CPS until the
lock tab snaps into place.

Test drive the vehicle for proper operation.

There are many reasons that could cause stalling or a rough running engine, the CPS is only one. If you changed your
CPS in an attempt to solve a stall or rough running problem and didn't fix the problem, don't throw the old one out as it is
probably still good. Keep it as a spare in the glove box because you never know when one of these will give out on you, usually
on the weekend when the dealerships and parts houses are closed. You will want to
pick up a new o-ring becase the one that came out with the CPS will never seal correctly and if reinstalled, will begin to drip oil down the front of the engine.
I have these o-rings made with genuine Viton available on my webshop for less than $2.00 each -

The Federalists Papers, Number 57, written by James Madison:

....... in the situation of the House of Representatives, restraining them from oppressive measures, that they can make no law which will not have its full operation on themselves and their friends, as well as on the great mass of the society. This has always been deemed one of the strongest bonds by which human policy can connect the rulers and the people together. It creates between them that communion of interests and sympathy of sentiments of which few governments have furnished examples; but without which every government degenerates into tyranny.
